Reconstructed Mediterranean Salt Lens Trajectories
Publisher: American Meteorological Society
Abstract: The existence of energetic anticyclonic mid-depth vortices of Mediterranean Water (meddies) questions the validity of a conventional advective?diffusive balance in the eastern Atlantic subtropical gyre. A mesoscale experiment ...
Numerical Modeling of Meander and Eddy Formation in the Azores Current Frontal Zone
Publisher: American Meteorological Society
Abstract: Numerical experiments with an 11-level primitive equation, finite-difference model in a periodic channel are performed to analyze the properties of unstable finite-amplitude disturbances in an idealized Azores Current. ...
Double Diffusion and the Distribution of the Density Ratio in the Mediterranean Waterfront Southeast of the Azores
Publisher: American Meteorological Society
Abstract: Temperture and salinity (T?S) finestructure on vertical scales of 10 db and larger is examined in a 500 by 500 km grid located southeast of the Azores in the North Atlantic. The convergence of several water masses dominated ...
Stochastic Wind Forcing of Baroclinic Rossby Waves in the Presence of a Meridional Boundary
Publisher: American Meteorological Society
Abstract: The quasigeostrophic response of a continuously stratified ocean to a band-limited white-noise windstress curl is examined in an infinite and semi-infinite ocean. Baroclinic Rossby waves?predominantly of first mode ...
Causes of Changes in the Denmark Strait Overflow
Publisher: American Meteorological Society
Abstract: The warming Nordic seas potentially tend to decrease the overflow across the Greenland?Iceland?Scotland Ridge (GISR) system. Recent observations by Macrander et al. document a significant drop in the intensity of outflowing ...
Cyclogenesis in the Denmark Strait Overflow Plume
Publisher: American Meteorological Society
Abstract: A densely spaced hydrographic survey of the northern Irminger Basin together with satellite-tracked near-surface drifters confirm the intense mesoscale variability within and above the Denmark Strait overflow. In particular, ...
The Sensitivity of the Greenland–Scotland Ridge Overflow to Forcing Changes
Publisher: American Meteorological Society
Abstract: Processes that influence the volume and heat transport across the Greenland?Scotland Ridge system are investigated in a numerical model with ?° horizontal resolution. The focus is on the sensitivity of cross-ridge transports ...
